Subject[PATCH 4.14 394/496] remoteproc: imx_rproc: Fix an error handling path in imx_rproc_probe()
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit de6f83f85be94e0b7d0d324c29ccc9d78a6bb4e7 ]

If 'of_device_get_match_data()' fails, we must undo the previous
'rproc_alloc()' call.

Fixes: a0ff4aa6f010 ("remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver")
